' Be it known t'liatl, Jon; ,J. Srrnnnm-m citizen of the United :Stotes,.residin at Waseca, in the county of Wasca; a-ncli tote of Minnesota,have invented oertoininewland useful Improvementsin Chimney-.fileanei's,of which the following ise'specificetion, reference being had to -theaooolnpenying clruwin 1 a:( i j This invention rel ates to chimneycleaners and the essential objeetro f the inrention is'to d provide adevice of this: churns-ten of-s'iifiple construction which is cheap tomanufacture and which maybe speedily operated to cler'rn n flue orchimney from anyvneeuniulstion pf soot or othevforei 'n mutter.

- Another object othe invention-is Q- P o ide. o eye vicle a; finecleaner which is adjustable to= 'uc-.

amount -of adjustment chimneys will clean respective oi the necessary.In a the brushes or clennin lements sothat they. miss a large portion 0the surface of the flue or chimney and thus failto clean the someproperlg. This invention absolutely avoids such a. c I modete itself tochimneys of vs. iug drone cter throughout their 1 h, sue as chimneyswhich are larger at t 0 bottom than at the to A fiirtlier object of theinvention, therefore, is to provide a device of this character whichwill adjust various irregularities of a flue or chimne which cannotstick or wed in the flue, on which will not injure the l ning of theohmimy in any manner.

A still further object of the invention 15 the revision of a device ofthis character whi will effectively clean a. chimney having eitherarectal: lar or circular flue and which will automatically accommodatetself cross sect on dimensions of the flue as will be more fully uparont hereinafter. 1

Secured to the rod intermediate its ends is a head 6 in the formofa,crow bar and ivoted to the outer ends of this bar are the rushsupporting and carrying arms 7, normally forced away from each other bythe leaf 5 rings 8 which are securecl'to the rod. 1 an bear against theinner sides of the arms'f, thus normally acting to throw the lower endsof the arms outwardly in opposite directions and thebrushes 9, carmedupon the lower on s of the arms, into engagement with the flue wall,which has through the backs thereof the attaching bolts 11 which passthrough" the lower ends of the arms and have threaded thereon the nuts12, and ii desirable, suitable lock nuts, not shown. When the nuts 12are clam :1

up on the bolts, the brushes will be hel in myndjusted position and itwill be understood that may be rotated upon the bolts or bestatmncrywith the bolts and the bolts rotated in the arms so as to secure anymdjustmentangulsrly of vthe arms whereby brushes of greater width-thanthe diam ter of the flue may be adjusted to operate in said flue and tocontact all over one side 'thereof, as will be readily understood frominspection of Figures 2 and 4. The brushes shown in Figures 1 and 2 aresemi-circular and when properly adjusted upon the arms are adapted tocompletely fill the flue, while the brushes shown in Figures'3 and 4 arerectangular in outline, being substantially oblong and are adapted toengage opposite sides of a rectangular flue.

When the brushes shown in Figures 3 and 4 are used, they are adjusted tocompletely cover opposite sides of the fiue and the device is loweredinto the chimney by means of the cable or chain 3 and worked up and downeither with or without the weight, according to conditions, untiloposi'te sides of the rectan ular flue have can completely cleaned. Thedevice is then turned a quarter revolution so as to operate against theother sides of the rectangular flue and the operation proceeded with asbefore. In a. circular flue the device may be operated up and down in asimilar manner and .turned whenever desired without removing the samefrom the flue. It will be noticed that by adjusting the brushes in arotary direction u on the arms that'I am enabled to complete l each sideof the flue and by utilizmg the freel pivoted arms and the springs8-,the brgs es are constantly kept in'contact wilh cover walls of theflue irrespective ofany variation or irregularity in the cross sectional dimension thereof, thereby insuring contact of the brushes withthe entire surfacelof the flue which efiectively cleans the same at allpoints,

Instead of using the cable or chain 3 and lowering the device into theflue by reason of gravity, 1- anay attach to the rod 1, as shown in Figure 5, a sectional rod 4 by which the c eener may 'be pushed downwardly into the flue and as it is removed, the sections can bedisconnected.

While I have illustrated a specific embodiment of my invention, I wishit to be clearl .understood that various changes and modi cations may hemade without inany way depertng from the spirit or scope of the appendsclaim and many. of these chan as are contemplated and will be re sorteto in practice.

What Icleim is:

In a. line cleaner, a sutpporting head, arms freely pivotal to' saisupporting, head, springs for normally forcing the freeends of the armsoutwardl in opposite directions, and brushes ad ustabIe' in'a rotarydirection upon'the free'ends ofthe arms, said-brushes having alengthufiial to or greatenthen the width of the He to be cleaned. 1
